' Application filed July 20, 1914. Serial No. 852,079.

To all whom it may concern:

Be it known that I, EDWIN S. PHELrs, a citizen of the' United States, residing at Elizabeth, in the county of Union and State ofNew Jersey, have invented certain new and useful Improvements in Time-Recording Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains t0 makeand use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention" relates to time-recording locks in which the operation of throwing the bolt to its locked and its unlocked position as well as the period of time the bolt remains in each position is marked or inscribed upon a record sheet so that the time the bolt is thrown and the time the door remains in both its locked and unlocked con ditions may be readily ascertained from an inspection of the record-sheet and preserved for reference by filing the record.

The primary object of the present inven tion is to make practically a duplex record in the record sheet of one. position of the lock-bolt compared with the record made of the lock in its other position so that the distinction between the two markings indicating the two different positions of the bolt is emphasized and thus a comparison of one with the other will make plain which record indicates one position and which the other and without having in mind other than the two distinctive markings. By duplex is meant either more than one line for one position of the bolt, or a heavier line which in effect is a merger of the dupleX lines and differentiates over a lighter line for recording the other position of the bolt so that a comparison of the two records readily distinguishes onefrom the other by the contact between the two.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be defined in the claims, reference being had to the accompanying drawings forming a part hereof, and in which:

Figure l is a front elevation of the recording lock, with its casing in section; Fig. 2 is a side elevation, with the casing in section; Fig. 3 a detail View, on an enlarged scale, looking from the rear and showing the position of parts. when the bolt is in its unlocked position; Fig. i is a plan view of a portion of the clock and other mechanism when the bolt is in its unlocked position; Fig. 5 is a detail, of a marker or stylus, on an enlarged scale, and portion broken away, looking from the rear; Fig. 6 is a View similar to Fig. 3, showing the position of parts when the bolt is in its locked position under a modified construction of stylus; Fig. 7 is a side view of parts of the device showing a modified form of stylus; Fig. 8 is a detail of a portion of the modified stylus, on an enlarged scale; Fig. 9 is a view similar to Fig. 4, embodying the modified stylus, and indicating its position when the bolt is in the locked position.

In the drawings the numeral 1 designates a casing of any approved construction within which is contained a lock-bolt 2 that may be operated by a key applied at 3 or by a key applied to turn a spindle 4 carrying studs 5 engaging a rack 6 forming a part of the bolt and which is a well known construction. In the upper portion 'of the casing is a clock mechanism of any approved type whose train of gearing is connected by a toothed wheel 7 with a toothed wheel 8 which carries a pinion 9 meshing with a pinion 10 which meshes with a toothed wheel 11 to which is connected a snail 12 for progressively moving the stylus ina radial direction when the device is to make a record for a period of more than one day if it be so desired, and all of which is also a well known construction and therefore needs no more detailed description. The shaft which carries the toothed wheel 8 has mounted thereon a hub 13 between which and thewheel S is a friction clamp 1 so that the hub may turn with the wheel and at the same time be rotated independently thereof for adjustment of a disk or dialplate 15 which carries a record receiving dial 16 of suitable material marked radially to represent hours and fractions of hours of a day and which is attached to the disk or dial plate by studs 17 and a spring clamp 18 held by a thumb-nut 19 and having a plate 20 back of the record receiving dial where the record inscriptions are made, all of which is also well known and merely illustrated as a suitable construction in connection witi which the present invention may be used. An arm 21 bears on the periphery of the snail and forms a part of a sleeve 22 suitably journaled and designed to support a stylus to move the same radially when the device is more than a one day recorder, said parts thus generally stated likewise being a well known construction.

Coming now to the present invention, the numeral 23 designates a rotatable spindle which in the form illustrated passes through the sleeve 22 and at one end carries the stylus 24: and at the other end is provided with a crank-arm 25 adjustably secured by a set screw 26 to the spindle and to which is pivotally connected one end of a pitman 27 the other endof which is pivotally attached to one arm 28 of a bell-crank lever or dog 29 mounted upon a shaft 30 or otherwise supported, and the other arm 31 of which is disposed so as to bear upon the top face or edge of the lock-bolt 2.

The stylus 24: is preferably carried by the sleeve 22 and also has a member thereof connected to the spindle which passes through the sleeve so that in one position of tl e bolt the stylus will make one char acter of record on the recordreceiving member and in another position of the bolt will make adifferentiating or contrasting character of record on the record-receiving member. The preferred form of the invention for this purpose is illustrated in Figs. 1 to 6 of the drawings. In such figures the stylus is of a type whose marking point or nib is deflected laterally under a spreading or scissors-like action to make a relatively broader marking for one position of the bolt than for the other position of the bolt, although the marking point or nib may be otherwise deflected for the same purpose as later mentioned. In the figures referred to, the stylus is formed of two arms or fingers 32 pivotally connected together by 1 apivot 33 which also connects the two arms to a support 34 which is preferably of spring metal and connected at one end by a set or adjusting screw 35 to the sleeve 22, one end of the spring support bearing against a boss 36 011 the sleeve so that by adjusting the screw the tension of the spring support will be varied so the pressure of the point or nib 38 of the stylus against the record receiving member will be varied as desired. One

end of the spindle 23 carries an angular or flat stud 39 made integral with the spindle or secured thereto by a pin 40 and which extends between the rear ends of the arms constituting the stylus so that when the spindle is turned to place the stud in one position it will spread the arms apart so that the divided point or nib of the stylus will be laterally deflected or spread so that at such time the stylus will make arelatively wide or broad record, for instance by two parallel lines as indicated in Fig. l of the drawing; and when the spindle is turned so as to bring the flat portion of the stud parallel with the two arms of the stylus, the divided nib of the stylus will be brought together or closed, which action will be facilitated by the spring as connecting the two arms of the stylus, so that the stylus will make a relatively narrow marking record or single line, such line also being shown in Fig. 1. The stylus is represented in Fig. 1 as beginning to make a relatively broad record.

The deflection of the marking point or nib of the stylus is effected as follows: It will be observed (Fig. 1) that the bolt 2 is formed in its top edge with two cavities 43, although one cavity may be omitted. The bolt is represented as retracted or in unlocking position. At such time the lever arm of the bell crank lever or dog lies in a cavity of the bolt and the pitman is in its lowered position, and the nib of the stylus deflected as illustrated in Fig. 1 so that the two parallel record lines will be formed and which indicate the unlocked position of the bolt. When the bolt is projected or thrown to locking position, the bolt lifts the lever arm of the bell crank dog or lever which throws the pitman upward and through its crank connection with the spindle 23 turns the latter so as to bring the flat side of the stud 39 parallel with the two arms of the stylus which will then be drawn together by the spring 42 so that the divided nib of the stylus will be closed and then a relatively fine or narrow line such as indicated in the drawing (Fig. 1) will be made and this will indicate the locked position of the bolt. By having two cavities as in the bolt 2 the nib of the stylus will be contracted when the lever arm of the bell crank lever passes from the first cavity to the top edge of the bolt and then be spread or opened when the arm drops into the next cavity and then brought together again when the arm again comes to the top edge of the bolt. Thus a llBilVlB-l line is made in a radial direction to indicate clearly the moment of time when the bolt is thrown either forward or backward and that marking emphasized.

The numeral 44 designates a spring for a prompt restoration of the pitman to its lowermost position when the lower arm of the bell crank lever enters the cavity in the lock-bolt; and 4:5 designates a spring which holds the arm 21 against the periphery of the snail 12 under a spring tension.

In the modified form of stylus illustrated in Figs. 6 to 8 of the drawing the spring support 34 of the stylus carries at one end the marking point or nib consisting in this instance of an oscillatory stem 46 passing through the spring support and having a chisel-shaped edge 47 to bear against the record receiving member and at its opposite or outer end provided with a crank 48 secured thereto by a set screw as and to which is pivotally connected one end of a bar 50 th opposite end of which is pivotally connected to a crank 51 attached by a set screw 52 to the end of the spindle 23. Otherwise than as specified the other parts of this embodiment of the invention are the same as described for the other form. Under this modified form of stylus when the bolt is in its locked position and the lower arm of the bell crank lever is in the cavity of the bolt the members of the stylus are in the position illustrated in full lines in Figs. 6 to 8 of the drawing and the chisel-edge of the marking nib is presented to the record receiving memher with its straight edge parallel with the length of the connecting bar 50 so that it makes a relatively narrow or hair record line on the record-receiving member, and which indicates one position of the bolt, which under the illustration given is the locked position. When the bolt is roiected or thrown into its locked position the lower arm of the bell crank lever rides on the top edge of the bolt which lifts the nitman and oscillates or rocks the spindle 23 so as to throw the cranks i8 and 51 and connecting bar 50 to the position shown by dotted lines in Fig. 7 which will deflect the chisel-edge marking nib laterally so that its edge will stand at an angle of ninety degrees, more or less,'to its former position which will cause it to make a relatively wider or heavier marking record as indicated in Fig. 7 of the drawing.

It will be observed that under both embodiments of the invention one position of the bolt is indicated by a relatively thin or light line and the other position by a relatively wider or heavier record line, the relatively wider record line under one form of stylus being two parallel lines spaced apart, and under the other being practically a merger of the two parallel lines so as to make one heavy or broad line. Both forms however contain the embodiment of a relatively light record line to indicate one position of the lock and a relatively wider record to indicate the other position, so that the locked and unlocked positions are indicated by sharp contrasting lines. An observation of these lines and consideration of them in relation to the scale indicating the hours and fractions thereof afford a record reliably indicating when the look was thrown to each position and the period of time it remained in each position, that is locked and unlocked.

What is considered to be the best embodiments of the invention have been illustrated and particularly described but it will be obvious "that changes may be embodied in details and essential features of the invention retained.

I have illustrated the invention used with a record-receiving member consisting of a flat record-sheet attached to a corresponding shaped dial-plate but the invention involving the characteristic markings specified for it is' the same irrespective of the form of the record-receiving member and its supporting plate whether they be flat or cylindrical.

Having described my invention and set forth its merits what I claim is 1. A time recording lock comprising record-making mechanism including a record receiving member and a recording stylus cooperating therewith, a lock-bolt, and means connecting the lock-bolt with the recording stylus and serving to deflect the stylus to effect a relatively broad record to indicate one position of the bolt and a relatively light or narrow record for the other position of the bolt.

2. A time recording lock comprising record making mechanism including a recordreceiving member and a recording stylus cooperating therewith, the stylus having a spreadable marking nib, a lock-bolt, and means connecting the lock-bolt with the recording stylus and serving to spread the marking nib to form a relatively wide record for one position of the bolt and permit contraction of the nib to form a relatively light or narrow record for the other position of the bolt.

3. A time recording lock comprising record-making mechanism including a recordreceiving member and a recording stylus cooperating therewith, the stylus comprising pivotally associated members having a spreadable marking nib, a lock-bolt, a lever associated with the bolt for actuation from the bolt, a spreading member associated with the pivoted members of the stylus, and a pitman connecting said spreader and lever to expand the marking nib to form a relatively wide record for one position of the bolt and permit contraction of the nib to form a relatively light or narrow record for the other position of the bolt.

4. A time recording lock comprising record-making mechanism including a recordreceiving member and a recording stylus cooperating therewith, the stylus having a deflectable marking nib to form a relatively wide record in one position and a relatively narrower record in another position, a lockbolt, and means for deflecting the marking nib of the stylus according to the locked or unlocked position of the bolt to efiect the two characters of record.

5. In a time recording lock comprising a record-making mechanism including a record-receiving member and a stylus, a spring support for the stylus, the stylus being connected to said support to move thereon in the plane of the record-receiving member, and means for adjusting the spring support to vary the tension of the marking nib against the record-receiving member.

(3. A time recording lock comprising record making mechanism including a recordreceiving member and a recording stylus cooperating therewith, a snail, a sleeve carrying an arm in engagement with the snail and carrying the stylus to move the latter radially, a deflectable marking nib to the stylus, a spindle passing through the aforementioned sleeve and connected with the nib of the stylus for deflecting the nib to change the indicating character of its record, a lockbolt, and connecting means between the lockbolt and the aforementioned spindle to effect a deflection of the marking nib in the movements of the bolt.

In testimony whereof I afiix my signature in presence of two witnesses.
